At Least Twice A Year - Chevrolet 2003 Silverado 1500 Pickup Owner's Manual

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside
of
Your Vehicle on page 5-105.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the wheel
wrenchhatchet to tighten the cable. See Changing a Flat
Tire on page 5-84.
6-1 2
Engine Air Cleaner Filter Restriction
Indicator Check (If Equipped)
Your vehicle has an indicator located on the air cleaner
in the engine compartment that lets you know when
the air cleaner filter is dirty and needs to be changed.
Check indicator at least twice a year or when your
engine oil is changed, whichever occurs first. See
Engine Air Cleaner/Filter on page 5-23 for more
information. Inspect your air cleaner filter restriction
indicator more often if the vehicle is used in dusty areas
or under off road conditions.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See Part D: Recommended Fluids and
Lubricants on page 6-18.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
Manual Transmission Fluid on page 5-31. Check
for leaks. A fluid leak is the only reason for fluid loss.
Have the system inspected and repaired if needed.
